Q33 / 97 · NTA Abhyas (JEE Main) 2020 · Physics · Nuclear Physics
The particle is converted into via the following reaction.
Then
Then
- AA and C are isobars
- Correct answerBA and C are isotopes
- CA and B are isobars
- DA and B are isotopes
Solution
Let be the mass number of and the atomic number. Then , since atomic number and mass number remain conserved, we have
Hence, we observe that and are isotopes as their atomic numbers are same but mass numbers are different.
Hence, we observe that and are isotopes as their atomic numbers are same but mass numbers are different.
Hence, the correct answer is option: 'B'.
